Devon Bowie, 19, was booked into Parish Prison with second-degree murder and illegal use of a weapon.

He is accused of killing Patrick Williams on Jan. 13 at the home he and Williams both shared with Williams' grandmother on St. Joseph Street.

Bowie's sister told police she was in the kitchen when Bowie said he was leaving, according to his arrest warrant. About 10 seconds later, she heard gunshots in the living room. She went to the living room and found Williams dead and her brother gone.

Police also received several tips from people who said they saw Bowie leaving the house with a gun in his hand just after hearing the shots, the warrant said.

Bowie's sister told police the relationship between him and Williams had been "turbulent" for two weeks prior to the shooting, the warrant said.

Williams' grandmother, Corine Stewart, said she and Williams were preparing to move at the time of the shooting. She has moved, but can't afford to bury her grandson.

Bowie remains in jail with bond set at $255,000, according to booking records.
